Switch to LARGE mode to merge both bays for up to 78TB of unified storage. (Note: Performance and capacity depend on your drives; see product page for RAID details.)

This external storage solution ensures your premium display performs at its absolute best while keeping all your drives connected in one streamlined setup.(Note: Your monitor needs to support 8K@60Hz.)
